an infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولMicrostrip Antenna Gain Enhancement using Near Zero Refractive Index Metamaterials
Some useful features of microstrip patch antennas are low profile, low weight and easy fabrication. However this type of antenna suffers from having a low gain, caused by propagation surface waves. In this paper, a new near zero refractive index metamaterial (MTM) unit cell is designed and fabricated as a superstrate over a Rectangular Microstrip Patch Antennas (RMPA). In order to obtain a maxi...
متن کاملMutual Coupling Reduction Using Dumbbell Defected Ground Structure for Multiband Microstrip Antenna Array
A novel design of multiband microstrip antenna array with dumbbell shape defected ground structure (DGS) is presented. The DGS is inserted into the ground plane between the two elements of the antenna array in order to suppress mutual coupling. Both simulation and measurement results verified that the DGS improved the radiation properties of the antenna array. Measurement results of the DGS ant...
متن کاملMutual Coupling Reduction of Microstrip Patch Antenna Array Using Slotted Ground Structure
In microstrip patch antenna array, the mutual coupling is very critical due to surface wave excitation. It leads to degradation in radiation pattern and reduction in gain. In this paper, a method to mitigate mutual coupling effect in an antenna array using Slotted Ground Structure (SGS) at 900MHz and dielectric constant 2.2 is simulated and analyzed using Ansoft HFSS 13. Simulated results show ...
متن کاملDesign of High Impedance Electromagnetic Surfaces for Mutual Coupling Reduction in Patch Antenna Array
A compact planar meander-bridge high impedance electromagnetic structure (MBHIES) was designed and its bandgap characteristics, mutual coupling reduction abilities were studied and compared in detail. Several parametric analyses were performed to obtain optimized design values and the transmission responses were calculated through the suspended microstrip line and waveguide simulation methods. ...
